Disclosed is a method of making drills, endmills and other rotating-and-cutting tools comprising the steps of: extruding super-hard metal powder into a spiral rod; sintering the spiral rod; forming a-ferrous metal powder layer around the rear end of the spiral rod sinter; and heating and then cooling the ferrous metal powder layer in such a way that voids may be caused to appear in the ferrous met...

The cage portion of a cage and roller assembly has two annular end rims joined by cross-bars around the periphery of each rim. The rims and cross-bars define multiple pockets which hold the rollers. The cross-bars are configured to contain the rollers within these pockets; in addition, coined ramp surfaces and land surfaces on the cross-bar outer surfaces extend radially outward farther than the o...

A microcomputer includes an interrupt signal generator for supplying a CPU with an interrupt signal at predetermined time intervals, and a monitoring timer reset by a reset signal generated by the CPU in response to the interrupt signal. An abnormality is sensed on the basis of expiration of time in the monitoring timer. A flag for resetting the monitoring timer during a first processing started b...

Polyethylene terephthalate scrap material containing on its surface a chlorine-containing polymer such as, for example, polyvinylidene chloride or polyvinyl chloride, can be recovered and reused by melt-blending it with a polymer from a defined class of ethylene copolymers containing an epoxy group, and melt processing the blend in the same manner as virgin polyethylene terephthalate. The recovere...
